Abstract

We consider the problem of generic broadcast in asynchronous systems with crashes, a problem that was first studied in [12]. Roughly speaking, given a "conflict" relation on the set of messages, generic broadcast ensures that any two messages that conflict are delivered in the same order; messages that do not conflict may be delivered in different order. In this paper, we define what it means for an implementation generic broadcast to be "thrifty", and give corresponding implementations that are optimal in terms of resiliency. We also give an interesting application of our results regarding the implementation of atomic broadcast.
